Description

Technical Field

[0001] The invention relates to the technical field of distillation, and in particular to a device and a method for preparing a biological protective agent. Background Art

[0002] Mosquito bites cause great trouble to people. Not only will the bitten area become swollen and itchy, but it may also lead to the spread of disease. Repeated bites can cause discomfort, irritability and anxiety, affecting the quality of life. Plants such as lemongrass, pine needles, mint and eucalyptus leaves contain natural biological control ingredients. Not only are their mosquito repellent properties widely confirmed, but the extracts obtained from them have a unique fragrance that can have many beneficial effects such as invigorating the spirit and making people feel happy.

[0003] Chinese patent CN210728722U discloses a mint distillation device, including a distillation box, a steam chamber is provided at the bottom of the distillation box, an air outlet is provided on the upper wall of the steam chamber, a collection hood that shrinks upward is provided on the top of the distillation box, a gooseneck is connected to the top of the collection hood, and the gooseneck is connected to a condenser. A plurality of mesh plates arranged at equal intervals are fixed from top to bottom inside the distillation box, and the mesh plates are tilted. A discharge door is provided on the side of the distillation box located at the lower side of the mesh plate, and a feed door is provided on the side of the distillation box located at the higher side of the mesh plate. This structure is very convenient for completing the process of loading and unloading mint, but the device still has the following problems:

[0004] 1. During the distillation process, steam flows from bottom to top, and it is difficult for steam to directly contact the upper layer of the stacked materials. The upper and lower sides of the materials are unevenly affected by steam, which reduces the evaporation efficiency.

[0005] 2. The raw materials used for distillation usually go through the processes of drying and crushing. The flowing steam will blow up the finely crushed raw materials and make them adhere to the filter, causing the filter to be blocked, affecting the extraction efficiency of the raw materials.
